Claims.

This invention relates tobake pan sets of the type employed in commercial bakeries and more particularly to pan sets having means for'maintaining the individual pans of -said pan sets in spaced relation when Ta plurality of said sets are stacked one upon another.

Pan sets employed in commercial bakeries usually comprise a plurality Y'of individual pans 'secured to either over or under-'wire bands in spaced relation to each other. The side and end walls of individual pans are tapered from vthe Vtopzedges towards the bottom sothat when a .pan

'set fis stacked Vupon another set, the portions .of the pans below'the bands extend intoy Lor nest within the pans of the set below zit. When pan Vsets are stacked, the bands rest .upon the rims of the end ywalls of the pans, in under-,wire banded seits, or upon the bands of the set `below in .over-wire banded sets. When pan sets are stacked, they should be held in .spaced relation and locked against both lateral and longitudinal movement to prevent rubbing of the pans against each other. The surfaces ofthe pans are thereby protected. The ,pan sets should also 'be so locked and braced when stacked, that the stack will not shift out vof plumb -when moved from place to place in a bakery.

An object o'f vthis invention is to provide a bake pan set with means for preventing lateral and longitudinal movement thereof when it is Stacked upon another similar bake pan set.

Another Object of the invention is to provide a bake pan set with means which when a pan set is stacked upon another, holds vthe body portions of the pans ofthe sets in spaced relation to each other.

The above and other objects and features of the invention will be `apparent to -those skilled in this art from the following description taken in conjunction withthe accompanying drawings, in which:

Throughout the drawings 'and the specication like reference charactersindicate like parts.

In`Figs."1,"2 and vr3 off'th'e drawings a stack of similarly constructed bake pan sets Al and B embodying a form f the `invention are shown. Each Ybake pan vset comprises a plurality of individual pans `l 'which' aresecured as a unit to end bands y2 and 3 and side'Y bands 4, the end bands 'and side "bands embracing the units.V The iridiviauar'pan's may be 'secured to the 'end bands inY any suitable manner as with rivets or by means of lap clinches as disclosedV in the'copending application 'of' Jesse L."Darnell and Elbert M. Cormack, 'Serial No. 98,084,"f11ed June 9. `1949. Also, pans I may be constructed `in the same manner as the pans lof 'that 'application are constructed. I prefer `the lap vclinch attachment of the'above mentionedapplication 'to rivets. In the lap clinch attachment the Vend bands are provided with a pair of inwardly disposed and downwardly projecting tabs '5 for each pan. These tabs extend'behind the respective fold-flaps 6 at each pan end. These tabsandaps are squeezed together after assembly so that the pans are firmly secured to the bands.

The pan sets are also provided with crossbraces l. These braces asfshown are secured to 4adjacent top edges ofthe side walls of adjacent pans, there being two cross-braces per pair of pans, although a large number may be used if the length'of thepans require additional crossbracing.

As shown in Fig. 2, the ,cross-braces are attached to the undersideof the rolled top edges of the side walls of the pans. A lso, as shown by Figs. 1, 2 and 3, the side and end walls 8-8 and 9-9 of 'the respectivepans taperor vslope inwardly from fthe topedgesto thebottom thereof, so that .when one lset A"is stacl'zked upon another the walls of the portions Aof the pans below the bands 2 and 3 are spaced from 4the walls of the pans within which they are nested, see Fig. 2.

In order to hold the pan sets in the spaced relation shown in Fig. 2, when pan sets are stacked, and. also .to ,prevent relative longitudinal Vand. lateralmovement of .the plan. sets, .means .are

provided for locking the nested pansets .in the spaced relationshipshown'in Fig. 2.' 'The locking means comprises a pair of bars l0 and Il. I prefer to locate the bars adjacent the innermost edges of the outermost pans in a. set as shown in Fig. 1.

Bar I is secured at its opposite ends to the end bands 2 and 3 at such a location that the lower edge of the bar is below the lower edges of the end bands and in substantially vertical alignment with the edge I2 of the pan. I prefer to mount bar l0 so that it is inclined at an angle and in a plane substantially parallel to side wall 8 of the pans. Thus when a pan set'is stacked on another set the bar lies against the edge I2 of the pan in the set immediately below.

Bar II is similar to bar IIJ and is mounted on the end bands 2 and 3 in the same manner. However, bar II is inclined in the opposite direction so that it lies in a plane substantially parallel to side walls 8' of the pans. By so inclining bars I0 and I I the lowermost edges thereof will clear the edges I2 and I 2 of the pans in the lower set and guide the pan sets into place.

Since bars I and II of one pan set bear against edges I2 and I2 of the outermost pans in a pan set immediately below it, the pan sets cannotmove laterally, that is to the right or left, relative to one another. To prevent movement of the pan sets relative to one another in a direction longitudinally of the individual pans I, bars I9 and II- are provided with notches I 4 and I5V located to receive the cross-braces 'I therein. The inner edges I5 of these notches abut` the inner edges I6 and I6 of the braces, and the pans of a unit are thereby locked against movement in Veither direction longitudinally of the pansf To facilitate sliding of a pan unit into place when stacking them, the portions of bars I0 and II between` the notches and the ends thereof may bebowed or arched downwardly as at I7 and Il 'to form skids or runners. These skids or`runners slide over the braces 'I as a pan unit' is stacked'on another unit. Ordinarily, stacking is done by placing one side thereof on which an end band 2 or 3 is secured over the opposite side of the lower pan unit and then sliding it into place. When sliding into place, the skids ride over the cross-braces without doing damage-to them;

The depth of each notch I4 and I5 is such that the barsdo not rest on the cross-braces to vavoid Vimposing the weight of a stack of pans on the braces Vin the lowermost units in a stack. VThe-bars III'and II may be secured to end bands `2 and V3 in many ways, however I prefer to securethem by means of clips I8 such as shown in Figs. 2 and 3.

Each clip I8 comprises a back 2G which is secured to the end bands preferably by welding it thereto, and spaced forwardly projecting tabs 2I and 22.-4 The ends of the bars are received between'tabs 2| and 22 and are secured thereto by welding or vother suitable means. By em- Therefore what I claim as new and desire to secure by Letters Patent is:

1. A pan unit comprising a plurality of spaced pans said unit being adapted for stacking upon another unit with the pans thereof nesting in the pans of another pan unit, each of the pans of said unit having side and end walls tapering from the top to the bottom thereof, bands extending across the ends of said pans and secured thereto to hold said pans together as a unit, cross-braces secured. to adjacent top edges of adjacent pans, a bar secured at its ends to said end bands and extending parallel to and lying substantially in the vertical plane containing a top edge of one of the pans of the unit, a second bar secured at its ends to said bands and extending parallel to and lying substantially in the vertical plane containing the opposite top edge of a different pan of the unit, the lower edges of the portions of the bars betweensaid endsjbeing Vat a level below the lowermost edges of said bands, said bars having notches inY their lowermost edges corresponding in location to saidv braces, said bars and the notches therein cooperating with the cross-braces of said other unit to space the individual pans of a unit from the pans 'of said 'other unit when nested therein and hold said pans against longitudinal and lateral movement when a pan unit is stacked upon another unit.

2. A'pan unit according to claim 1 characterized by the fact that said bars are disposed respectively adjacent the inside edges of the outermost pans of Ya unit.

3. Apan unit according to claim 1 characterized by the fact that the ends of the bars are secured to clipseach'of which clips has' aback secured to the end bands and ay pair of spaced tabsbetween which the endof a bar is received and to which the bar is secured.

4. A pan unit according to claim 1 characterized by the fact that the lower edges of the portions of the bars between the notches and the ends Vthereof are downwardly arched to form skid surfaces to facilitate sliding of a pan'unit into another pan unit when stacking the same.

'5. A pan unit according to claim 1 characterized by the fact that adjacent edges of adjacent pans are connected by cross-braces disposed one adjacent each end of each pan and that each bar is provided with a notch adjacent each end thereof disposed to receive the respective braces of another pan'unit, and that the lower edges of said bars between the notches and the ends thereof are downwardly bowed to form skid surfaces to facilitate sliding of a pan unit into anotherpan unit when stacking the same.
